We've seen plenty of pet capybaras on the internet by now (most famously Captain ROUS), but none of them have yet been nearly as geeky as the delightfully precious JoeJoe. He not only has posed in this cute little Batman story, he also has been known to dress in a great Batman costume of his own and pose alongside AT-AT's.

It just goes to show that even if you're among the the largest rodents on earth, you can still hope to grow up to be a giant crime-fighting bat.
